Keeping Faith and a Good Conscience.
1 and 2 Timothy have seventy-five commands for us to obey with intention and integrity. One of those commands is found in 1 Timothy 1:18-20. The word "faith" in verse 19 is synonymous with the word "command" in verse 18, so "keeping faith" could read "keeping the command."
The word "keeping" means to bear or wear the faith/command, allowing it to become part of our person. The faith is the body of doctrines written and preserved in the Word of God for us to obey.
Each of us is to keep this faith with a good conscience. A person’s conscience is well instructed and at peace when it knows and lives the commands of Scripture. Paul also mentions the conscience in 1 Timothy 1 and 3. Each mention is tied directly to the command of Scripture, the instruction of Scripture, and the mystery of faith pertaining to the Word of God and the gospel message of Jesus Christ.
